The Collins family wants to prevent child abduction while also sharing Elizabeth's story. A memory that's also close to her sister's heart.

"I remember i played with her a lot. We played Barbies and whenever I had an owie she would help me," Callie Collins said.

Even with no recent developments in this case the family remains hopeful an arrest will eventually be made.

Authorities are still hoping to find whoever kidnapped and murdered the two girls.
